Description

Technical Field

[0001] The invention relates to solar cell production equipment in the photovoltaic field, in particular to a welding strip tool conveying mechanism, a welding strip welding device and a welding strip tool conveying method. Background Art

[0002] When making solar cells, multiple cells need to be connected into a battery string. A cell string welding machine is an automated device for making battery strings.

[0003] During the battery cell string welding process, the welding ribbon needs to be coated with flux first, and then the welding ribbon is placed on the battery cell for welding. In order to prevent the position of the welding ribbon from shifting, the tooling will be placed on the battery cell to press the welding ribbon before welding. Since the welding ribbon is coated with flux at this time, the tooling will also be more or less stained with flux. If the flux on the tooling is not cleaned in time, it may not only contaminate the battery string, but also be stained with dust in the air. After the flux on the tooling dries, it will form hard dirt, affecting the use of the tooling. Summary of the invention

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] The present invention relates to a welding ribbon welding device, which is used to weld a welding ribbon to a battery cell. The present invention also relates to a welding ribbon tool conveying mechanism, which is used to clean the welding ribbon tool used in the welding ribbon welding device. The cleaned welding ribbon tool is placed on the battery cell on the welding ribbon welding device to press the welding ribbon.

[0037] Figure 1 , Figure 2 An optional embodiment of a welding strip welding device is shown. Figure 1 is a stereogram of the device. Figure 2 1 is a top view of the device. The ribbon welding device 100 comprises a welding conveyor belt 10, a first transport mechanism 20, a ribbon tooling transport mechanism 40 and a second transport mechanism. Two ribbon tooling transport mechanisms 40 are shown in the figure. A welding light box is also provided next to the welding conveyor belt 10, which is not shown in the figure. The welding light box is used to weld the ribbon 101 to the battery cell 102.

[0038] Figure 3 to Figure 5 The figure shows an optional embodiment of a welding strip tooling conveying mechanism. The welding strip tooling conveying mechanism 40 comprises a tooling conveying part 41 and a cleaning part 42.

[0039] Please see again Figure 1 and Figure 2 The welding conveyor belt 10 is located at one side of the tooling conveying part 41 and is used to transport the battery cells 102 and the welding ribbon 101. The conveying direction of the welding conveyor belt 10 is opposite to that of the tooling conveying part 41. Figure 2The middle welding conveyor belt 10 conveys from left to right, and the tooling conveying part 41 conveys from right to left. The welding conveyor belt 10 can adopt any form in the prior art, and generally adopts a belt conveyor.

[0040] The first transport mechanism 20 is located at the discharge end of the welding conveyor belt 10 and at the feed end 4111 of the tooling conveying part 41, that is, Figure 2 The first transport mechanism 20 spans over the welding conveyor belt 10 and the tooling transport unit 41. The first transport mechanism 20 is used to transport the tooling 103 from the welding conveyor belt 10 to the tooling transport unit 41.

[0041] The second transport mechanism (not shown in the figure) is located at the discharge end 4112 of the tooling conveying part 41 and at the feed end of the welding conveyor belt 10. Figure 2 The second transport mechanism is located between the tooling transport portion 41 and the welding conveyor belt 10, and is used to transport the tooling 103 from the tooling transport portion 41 to the welding conveyor belt 10. Optionally, the second transport mechanism uses a transport robot, which has mature technology and occupies a small space.

[0042] By setting a welding strip tooling conveying mechanism 40 on one side of the welding conveyor belt 10, the dirty substances on the tooling 103 can be cleaned online in time to prevent the dirty substances from contaminating the battery cells 102 and the welding strips 101 on the welding conveyor belt 10; the conveying directions of the welding conveyor belt 10 and the tooling conveying part 41 are opposite, which can shorten the moving path of the tooling 103 between the two conveyor belts and improve production efficiency.

[0043] Figure 3 to Figure 5 Shown Figure 1 The welding ribbon tool conveying mechanism 40 in the welding ribbon welding device 100 is shown. Figure 3 is a three-dimensional diagram of the organization. Figure 4 This is a top view of the organization. Figure 5 The welding strip tooling conveying mechanism 40 comprises a tooling conveying unit 41 and a cleaning unit 42 .

[0044] The tooling conveying part 41 is used to carry the tooling 103 and convey the tooling 103 from the feeding end 4111 to the discharging end 4112. The tooling 103 at least presses the welding ribbon 101 against the battery cell 102 before the welding ribbon 101 is welded to the battery cell 102. As an example, the tooling 103 shown in the figure is approximately in the shape of an "I". Of course, the shape of the tooling 103 is designed according to actual needs and is not limited to the "I" shape.

[0045] The cleaning section 42 is installed below the tooling conveying section 41 and is located between the feeding end 4111 and the discharging end 4112 , and is used to clean the tooling 103 passing over the cleaning section 42 .

[0046] By setting a cleaning section 42 below the tooling conveying section 41 of the transport tooling 103, dirty substances on the tooling 103 can be cleaned online in time, thereby improving the production efficiency of the battery cell 102 string welding device, preventing the battery cell 102 from being contaminated, and improving the quality of the battery cell 102.

[0048] The bracket 411 is made of steel plate and / or steel, and can be an integral structure or a split structure, that is, it can include multiple parts. The bracket 411 serves as a mounting base for other components.

[0049] The tooling conveyor belt 412 is installed on the bracket 411, and is used to carry and convey the tooling 103. Optionally, the tooling conveying part 41 adopts the tooling conveyor belt 412. The tooling conveyor belt 412, i.e., the transport belt, has a simple structure, is easy to maintain, and has low cost.

[0050] The driving device 413 is installed on the bracket 411 and is used to drive the tooling conveyor belt 412 to rotate. The driving device 413 can adopt any form in the prior art, and a motor and a reducer are commonly used to drive the driving wheel of the conveyor belt.

[0051] Alternatively, if Figure 3 As shown, the tooling conveying part 41 is further provided with two opposite guide devices 414 between the feed end 4111 and the discharge end 4112. The two guide devices 414 each include a baffle 4141 and a guide bar 4142. The two baffles 4141 are both located outside the tooling conveying belt 412 and are both arranged parallel to the tooling conveying belt 412. The guide bar 4142 is connected to the feed end 4111 of the baffle 4141. Along the conveying direction, the distance between the two guide bars 4142 gradually decreases until it is the same as the distance between the two baffles 4141.

[0052] The tooling 103 on the tooling conveyor belt 412 is guided by the guide device 414 so that the tooling 103 is arranged in order on the tooling conveyor belt 412 .

[0053] Optionally, the tool conveying part 41 is further provided with a tool regularization device 415 at the discharge end 4112. The tool regularization device 415 includes a stopper 4151, a regularization cylinder 4152, a first regularization piece 4153 and a second regularization piece 4154. The regularization cylinder 4152 is connected to the first regularization piece 4153, the first regularization piece 4153 and the second regularization piece 4154 are respectively located on opposite sides of the tool conveying belt 412, and the stopper 4151 is located at the end of the discharge end 4112.

[0054] When the stopper 4151 blocks the tooling 103 on the tooling conveyor belt 412 , the aligning cylinder 4152 drives the first aligning piece 4153 to move toward the second aligning piece 4154 to align the tooling 103 between the first aligning piece 4153 and the second aligning piece 4154 .

[0055] The tooling 103 on the tooling conveyor belt 412 is regulated by the tooling regulated device 415 so that the tooling 103 stays at a predetermined position, making it easier for the tooling 103 to be removed from the tooling conveyor belt 412 .

[0056] Optionally, the tooling conveying part 41 is further provided with a stop bar 4155 at the discharge end 4112. The stop bar 4155 is located on a side of the tooling aligning device 415 close to the feed end 4111 and adjacent to the tooling aligning device 415; the stop bar 4155 is located above the next tooling 103 of the tooling 103 aligned by the aligning cylinder 4152, and the stop bar 4155 blocks the tooling 103 below the stop bar 4155 from detaching from the tooling conveying belt 412 when the aligned tooling 103 is moved away from the tooling conveying belt 412.

[0057] The tooling 103 that has not been moved away is blocked by the blocking bar 4155 to prevent the tooling 103 from affecting the next tooling 103 when it is moved away.

[0058] Optionally, there are two tooling conveyor belts 412 , which are arranged in parallel. A tooling blocking device 416 is installed between the two tooling conveyor belts 412 .

[0059] The tooling blocking device 416 is located between the feed end 4111 and the discharge end 4112 and is close to the feed end 4111. After the tooling blocking device 416 rises, it blocks the tooling 103 on the tooling conveyor belt 412 from continuing to move in the reverse direction when the tooling conveyor belt 412 is transported in the reverse direction; or, the tooling blocking device 416 is located between the feed end 4111 and the storage end 4113 and is close to the feed end 4111. The feed end 4111 is located between the discharge end 4112 and the storage end 4113. After the tooling blocking device 416 rises, it blocks the tooling 103 on the tooling conveyor belt 412 from continuing to move in the forward direction when the tooling conveyor belt 412 is transported in the forward direction.

[0060] By providing the tool blocking device 416 , all the tools 103 can be recovered to the tool conveying part 41 when the ribbon welding device 100 finishes running, so as to facilitate the storage and arrangement of the tools 103 and reduce the floor space occupied by the storage of the tools 103 .

[0062] The cleaning unit 42 uses an ultrasonic cleaning device, which has mature technology, simple structure, low cost, and is easy to install and maintain. However, the cleaning unit is not limited to an ultrasonic cleaning device, and other cleaning devices such as a plasma cleaning device can also be used as long as the purpose of cleaning the tooling can be achieved.

[0063] Optionally, a storage box is installed below the cleaning unit 42. The storage box can collect the dirty materials cleaned from the tooling 103 to avoid contaminating the machine.

[0064] See also Figure 1 and Figure 2 An optional embodiment of the first transport mechanism 20 includes a traverse device 21, a lifting device 22 and a transport clamp 23. The transport clamp 23 is installed on the lifting device 22, and the lifting device 22 is installed on the traverse device 21. The lifting device 22 drives the transport clamp 23 to rise and fall, and the traverse device 21 drives the lifting device 22 to translate between the welding conveyor belt 10 and the tooling conveying portion 41. The traverse device 21, the lifting device 22 and the transport clamp 23 can adopt any form in the prior art.

[0065] The transport mechanism includes a transverse moving device 21 and a lifting device 22, which can adjust the position of the transport clamp 23 in the three-dimensional direction of space to grab the tooling 103, which is easy to operate.
